PolicyEngine US
For microsimulation, use policyengine.py. Society-wide microsimulation — population aggregates and distributional or budgetary impacts — is moving to the managed
policyengine.pybundle, which pins certified, calibration-gated datasets. Direct microsimulation viapolicyengine-us(Microsimulation()) is deprecated and being migrated topolicyengine.py. This package remains the home of the US tax-benefit rules and household-level calculations. Microsimulation results are estimates — inspect dataset calibration at https://calibration-diagnostics.vercel.app/populace.
PolicyEngine US is a microsimulation model of the US state and federal tax and benefit system.
PolicyEngine US supports Python 3.11 through 3.14 and requires pandas 3 or
later. To install, run pip install policyengine-us.
This release requires spm-calculator>=1.0.0,<=1.0.0.post1 (the canonical SPM threshold API).
Previously published country versions retain their original dependency metadata;
when reproducing one of those versions, include the compatible calculator
explicitly, for example:
uv pip install "policyengine-us==1.824.7" "spm-calculator==0.3.1"
To install PolicyEngine US as part of a certified PolicyEngine bundle, use the
bundle installer published by policyengine, for example:
uvx --from policyengine policyengine bundle install --country us --venv .venv
